An internal combustion engine is a
machine that converts
1.
heat energy to mechanical
energy through the burning of a
liquid fuel
2.
mechanical energy to heat
energy through the burning of a
liquid fuel
3.
mechanical energy to heat
energy through the burning of a
fuelair mixture within itself
4.
heat energy to mechanical
energy through the burning of a
fuelair mixture within itself
